If you own a Windows 11 laptop, tablet, or all-in-one PC, it’s easy to change your built-in screen’s brightness with a couple clicks (or taps) thanks to the Quick Settings menu or the Settings app. Here’s how.
How to Change Screen Brightness With Quick Settings
First, click the Quick Settings button in your taskbar, which is a hidden button located where you see your Wi-Fi, Speaker, and Battery icons in the far-right corner.
When the Quick Settings menu pops up, locate the brightness slider, which has a sun icon beside it. Click (or tap) and drag the circle on the brightness slider to increase or decrease the brightness of your built-in display.
In a nice touch, the sun icon grows larger or smaller depending on how bright you set the slider. When you have the slider how you like it, you can close the Quick Settings menu by clicking anywhere outside the menu or selecting the Quick Settings button in the taskbar again.
How to Change Screen Brightness in Windows Settings
You can also change your built-in screen’s brightness using Windows Settings. First, launch Settings by pressing Windows+i on your keyboard. When it opens, click “System” in the sidebar, then select “Display.”
In System Display settings, scroll down to the “Brightness & Color” section. Under “Brightness,” use the slider to raise or lower the brightness of your built-in display.
When you’re finished, close Settings. Whenever you need to adjust your brightness again, revisit Settings > System > Display or use the Quick Settings menu.
If Your Brightness Slider Is Greyed Out
If you don’t have a built-in display (like a laptop or tablet), the screen brightness slider in Quick Settings will be unavailable (grayed out). In that case, you’ll need to use your monitor’s physical controls to change your screen brightness. Consult your monitor’s support website or documentation to find out how to do that. Good luck!
